Be it known that we, FRuDuu-IGK SHICKLE and EVERMONT RANDALS, of St. Louis, in the county of St. Louis, and State of Missouri, llaveinvented a new and useful Improvement in Water Filters; and wedo hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, formingir part of this specification, in which- Figure '1 is a. vertical central section ofthe filter.

This invention relates to improvements in Water filters for filtering and purifying muddy water, and consists of pipes and chambers so connected and arranged that the muddy water shall pass from a receiving-chamber or reservoir through a ltering body of sand, gravel, charcoal, or other suitable porous and purifying compound into a supplychamber, from which vthe pure water is drawn off for use by a connected pipe and faucet. The principle upon which the muddy water is ltere'd and purified is by ascension or passing upward through the filtering compound to the supply-chamber of pure water, and leaving the mud andother impurities at thcbottom, instead of by the ordinary process of settling@r through the filtering compound fromV the top or sidcsQand depositing the mud, Snc., in or upon the filtering compound. 1he effect of filtering water upon this principle of ascension is that the filtering compound does not become choked 4and inoperative, but retains its porous quality, while the deposit of mud and other impurities may be easily removed by a current of water through a Waste pipe when necessary. A ball-cock is attached toithe filter for connection, when desired, with a water pipe for selfreglating supply. l l

A is the case o r body of the filter, made of'sheet-metal or other suitable material, of. any size and shape, according to its purpose, but for the use of private families it is made preferably like an ordinary water cooler, us represented, with a cover, a. The inside of the filter case A is divided into chambers or compartments by' partitions, one of which is the false bottom b, placed a few inches, more or less, according to size, above tho real bottom b', leaving between them a settling or mud-chamber, Bf Resting upon the false bottom I), is a central pure-water supply-chamber, C, formed by the partition or wall c, which extends half way or more up the body ol" the filter, and is open at the top, leaving an annular filtering-chamber D-betweea 'it and the case A. The' upper part ofthe chamber C is surroui'ided by a partition wu-ll, tid, which is joined at the lower part to the case A, and extends to the top where it is open, forming a kind of truncated conein the middle of the filter, leaving an annular space or receiving-chamber, E, between it und the case A. The top may be vpro\\idedwith a cover, c. A tube,fj`, passes from the bottom ofthe chamber E on the inside ofthe caso to the chamber B at the bottom. 1fitted into tho upper end of the pipeff, is a movable air-tube, gg, which runs down from thevtop. Near the lower end is made a small holo, le, in the side of tube, for the admission of wateiyas indicated by the arrow, tig. 1. rlhe annular chamber D is the filtering-chamber, and is illedwith the compound of gravel and sand or other materials used for the purpose. The false bottom b is perforated with small holes under the chamber D. A draw pipe, t', with a faucet attached, runs from the central chamber C tothe outside of the filter-case A, and awaste pipe, lc, with a faucet, leads from the' mud-chamber B. In the upper part of the filter is placed an ordinary hall-cocl in, for seltsupply, when desired, connected with a water pipe, n, fig. The water is first introduced into the annular chamber E, and passes through the hole t in the aix" pipe g, down through the' pipe f to the chamber lliY whence it ascends through the holes in the false bottom l) into the filtering-chamber D, and, percolating upward through the filtering compound, rises to the supply level and lls the chamber C, and the open space above, inside of .the conical wallscZ (Z, with pure water, as shown in lig. 1, which is drawn olf through/the pipe z'. More or loss muddy deposit will constantly form at the bottom of the chamber E, which may be removed daily, or as often as required, by lifting ythe loose tube g, and allowingjr it to run down the pipef, and when mud accumulates in the chamber B it is readily cleaned out by opening the waste pipo It. The bottom b is made a V little shelving, toward the outlet to clean it more thoroughly.

Having thus described the construction and operation of our` inve ntion, what We claim as new, and deslte to secure by Letters Patent, is-

The water filter-, onssting of the annular receiving-chamber E, filtering-chamber D, supply-chamber C, surroundved at its upper partby the partition wall d vl, tubeff, air-tube g,`a.nd mud-chamber B, when constructed and arranged as herein setforth for the purpose speoifed.
